Description

Technical Field

[0001] This utility model relates to the field of wear detection technology for pump station units, and specifically to a wear detection device for pump station unit maintenance. Background Technology

[0002] A pumping station is a comprehensive engineering facility specifically designed for lifting, transporting, and distributing liquids (such as water, sewage, and oil). It typically consists of several parts, including pumps, valves, pipelines, control systems, power supplies, and necessary auxiliary equipment, to achieve the purpose of increasing the pressure, height, or flow rate of the liquid. In a pumping station, a "unit" usually refers to a complete equipment unit, including one or more pumps and their drive devices, couplings, bases, bearings, lubrication systems, frequency converters (if any), power supplies, and necessary control and protection systems. To improve the reliability and safety of the equipment, it is necessary to regularly inspect the wear condition of the rotating shafts in the pumping station unit to avoid sudden shutdowns and reduce safety hazards.

[0003] A document with publication number CN222165916U describes a wear detection device for large pumping station units, relating to the technical field of water conservancy engineering maintenance equipment. It includes a fixed base and a detection ring mounted on the fixed base. The detection ring is movably and coaxially sleeved on a motor shaft. The base also has two sets of fixed frames, coaxially arranged with horizontal axes and open tops. The motor shaft is mounted on the two sets of fixed frames, and the detection ring is positioned between them. The detection ring has multiple sets of detection elements, with the elements near the ring's axis movably fitting against the outer surface of the motor shaft. The detection ring is rotatably mounted on the fixed base, which also includes an adjustment mechanism for adjusting the angle of the detection ring. This application simplifies the detection efficiency of motor shaft wear and improves the accuracy of motor shaft wear detection, thereby facilitating the assessment of the motor's normal service life.

[0004] The wear detection device disclosed above causes continuous friction between the detection head and the rotating shaft during the detection process. This continuous friction increases the local temperature rise, shortens the service life of the detection device, and in severe cases, can lead to misjudgment by the detection device.

[0016] This embodiment provides a technical solution: a wear detection device for pump station unit maintenance, such as... Figures 1-4As shown, the system includes a testing platform 1 and a testing mechanism 3. The testing platform 1 is equipped with a driving mechanism 2, which includes a lead screw 21 rotating inside the testing platform 1, two rods 22 fixed inside the testing platform 1, rotating positioning hoops 23 rotating on both sides of the top of the testing platform 1, and a servo motor 24 fixed to one side of the testing platform 1 by a mounting bracket.

The movable seat 31 slides on two rods 22. An annular seat 32 is fixed on the movable seat 31. The shaft to be tested passes through the annular seat 32. The annular seat 32 is provided with a detection element for detecting the wear degree of the shaft. The annular seat 32 is provided with at least two annular grooves 33. The number of annular grooves 33 is the same as the number of detection elements, and each annular groove 33 corresponds to one detection element. Adjacent annular grooves 33 are connected by a series groove 34. All annular grooves 33 are provided with two air outlet grooves 35. The opening end of the air outlet groove 35 is located on the inner side wall of the annular seat 32. A cooling element is provided on the movable seat 31.

[0018] The cooling component includes a cooling shell 36 fixed on a movable base 31. A cooling water pipe 37 is provided inside the cooling shell 36. A semiconductor cooling chip 38 is provided on the cooling water pipe 37. The cooling end of the semiconductor cooling chip 38 is located on the cooling water pipe 37, and the heat dissipation end is located outside the cooling shell 36. As is well known to those skilled in the art, the working principle and wiring method of the semiconductor cooling chip 38 are common and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience. An air pump 39 is fixed at the bottom of the cooling shell 36. The air outlet of the air pump 39 is connected to the cooling shell 36. The top of the cooling shell 36 is connected to the series groove 34 through a flexible hose. The cooling component also includes a telescopic component provided inside the annular base 32 and an annular tube 310 fixed on the telescopic component. The annular tube 310 surrounds the detection head 317. A guide nozzle 311 is provided on the annular tube 310, and the guide nozzle 311 faces the detection head 317.

[0019] The telescopic component includes two fixed cylinders 312 fixed to the inner wall of the annular seat 32. Sliding cylinders 313 are slidably sleeved on the inner side of each of the two fixed cylinders 312. The number of sliding cylinders 313 can be set by the user. When all the sliding cylinders 313 and fixed cylinders 312 are in the extended state, their length is adapted to the maximum displacement dimension of the detection rod 316. One end of each of the two sliding cylinders 313 is fixed to the annular tube 310. Telescopic tubes 314 are provided on the inner side of each of the two sliding cylinders 313. One end of each of the two telescopic tubes 314 is fixed to the opening of each of the two air outlet slots 35. The other end of each of the two telescopic tubes 314 is connected to the annular tube 310.

[0020] The testing component includes a hollow cylinder 315 fixed on an annular seat 32. A testing rod 316 slides on the inner side of the hollow cylinder 315. A testing head 317 is fixed to one end of the testing rod 316. A spring 318 is fixed between one end of the testing rod 316 and the inner wall of the hollow cylinder 315. The hollow cylinder 315 is fixedly connected to the sliding cylinder 313 through a connecting plate.

[0021] In use: The shaft to be tested is passed through the two rotating positioning clamps 23, which fix the shaft to be tested. When the spring force of the spring 318 returns to its original position, the detection head 317 can fit against the outer surface of the shaft to be tested with different diameters. Then, the servo motor 24, the detection piece, the air pump 39 and the semiconductor cooling chip 38 are started. The servo motor 24 will drive the rotating positioning clamps 23 and the shaft to be tested fixed on the rotating positioning clamps 23 to rotate through the synchronous belt 25. At the same time, it will drive the lead screw 21 to rotate. The rotation of the lead screw 21 causes the moving seat 31 to move straight along the rod 22, thereby driving the detection head 317 on the inner side of the ring seat 32 to move on the outer surface of the shaft to be tested. The rotation of the shaft is used to perform a comprehensive test on the shaft.

[0022] During testing, air pump 39 draws outside air into the cooling housing 36, which then passes through the cooling water pipe 37. The water in the cooling water pipe 37 is cooled by the semiconductor cooling chip 38, thus cooling the air to a low temperature as it passes through the cooling water pipe 37. The low-temperature air then enters the series groove 34 and each annular groove 33 through the hose, and enters the telescopic pipe 314 and annular pipe 310 through the air outlet 35. Finally, it is blown onto the detection position of the detection head 317 and the shaft through the guide nozzle 311, thereby helping to reduce the temperature generated by friction between the detection head 317 and the rotating shaft, thus helping to improve the service life of the detection device and avoid misjudgment by the detection device.

[0023] When shafts of different diameters come into contact with the detection head 317, the detection head 317 will drive the sliding cylinder 313 to slide upward, thereby driving the annular tube 310 and the telescopic tube 314 to move upward, thus ensuring that the guide nozzle 311 can always be aligned with the detection head 317 to ensure the cooling effect.

[0024] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
